Ask HN: Feedback on my SaaS venture (webdeveloper oriented)

I've been quite busy building my SaaS app, and now I'd would love to get your feedback on both the design and idea.

Does all my code pass through your server? That would be a problem.

The code that is being processed is retrieved / posted from and to GitHub (others in the future), but are never saved on the servers at any point.
